Flushing the Loo every time it is used (If it's yellow let it mellow, if
it's brown flush it down)
If you flush 5 times less per day you save over 3500 gallons a year.

Not always a good idea!

We tried it here, and the drains blocked, costing £shedloads to have
them cleared. There are similar stories about... One story I recall is
of someone whose neighbours did this, leading to expensive
drain-unblocking every three months. We costed it here and it's
cheaper to flush the loo each time. So far...so good.

It seems that in some circumstances some house drains need more water
going through them than is immediately obvious.
